It was strange only seeing Yuki briefly on Saturday and just the daytime on Sunday. At least Sachiko and Yumi helped by skipping the next Saturday class, giving me from midday til about one-forty to be alone with her. Yuki had given up wearing panties to my place since they came off at the door and went into my trophy drawer.
"I need to be more careful kissing you. Gee, the bruise on your breast, I didn't realize I was so rough," I said guiltily as I ran my hands over her bare skin.
"It's okay, I could cover it at home. The girls at work saw, but it's okay, I said a man got overexcited having sex with me. They laughed, they said they know what I mean. Nurses get that a lot."
"Your cunt is starting to stretch," I said, spinning her to hump from behind, standing in front of the phone filming us fuck. "I can feel it's bigger in there."
"It's been used a lot," Yuki said, blushing noticeably.
"No reason to feel bad. Letting your boyfriend fuck your cunt makes you a great girlfriend. Nothing to be embarrassed about."
I could feel Yuki shudder, but I shrugged it off, gripping her tits and swearing brutally at the joy of fucking her cunt as I lost my load deep inside my girlfriend's pussy.
Yuki walked comfortably around my apartment naked afterward, letting the leakage flow down her thigh. More and more she was carrying herself as Sachiko did, standing tall, pushing out her breasts to be fondled and sucked.
"So whose are all these?" she asked, one hand going through the contents of my trophy drawer, the other hand toying with the leakage from her used vagina.
"You want to know all my past sex life?"
"You know all of mine," she said, though that wasn't entirely true.
"What do you want to know?"
"How many of these are from Japanese girls?" she wanted to know.
I walked up behind Yuki, pushing my nudity against hers. I pulled out three pairs of panties and two bras.
"So many?" she asked.
"No, it's just one girl."
"Oh, it took her a while to learn to not wear underwear to your place?" she teased.
"Just like you," I said, holding up multiple pairs of her own.
"Who was she?" Yuki asked.
"A friend of Dean's girlfriend. He doesn't know, though. You can't tell him."
"Why not?"
"I give him shit about dating a high school student, but he never slept with his girlfriend while she was at school, not properly. If he knew his girlfriend's best friend was round here leaving her pants in my drawer, I'd never live it down."
"You had sex with a high school girl?"
"She didn't look like a high school girl, not with her clothes off."
"My god, how old was she?"
"She'd turned eighteen already, I'm not that silly."
"Oh my god, imagine if you got a high school girl pregnant!"
"I know. There were a few worried moments, she didn't use contraceptives. She saw the doctor a few times, but thankfully she was never pregnant."
"You had sex with her in her uniform?" Yuki teased me.
"Of course," I grinned, "That was the fun bit, she wanted it, too. She used to come here straight from school with no panties on, had them off all day, waiting to come here. She liked being cum in fully dressed for school, sometimes on the way to school, too."
"Oh, you want me to bring my nurse uniform over one day?"
"We can try!" I smiled, thumbing her breasts.
"So what happened to her?" Yuki asked, holding the high school girl's tiny pants up. "She can't have been very big. These are small."
"Left high school, went to uni in Kyoto. We weren't dating anyway, we never went out anywhere. She just came here for sex."
"Hmmm, that was never me," Yuki said with a deep breath. "At high school, I didn't want any sex. Seemed like something messy to me."
"How about now?" I asked, moving her hand to finger her pussy.
"I'm a woman now. I should be doing this now. I can try anything now, I think. I should try, right? As you said. High school is too young."
"Well, she was... happy to get it," I defended.
"How often was she here?"
"Most days until exams started. But it was just fuck and go, she didn't hang around."
"Didn't you have to work?"
"I was teaching junior high back then. That one, over there," I pointed out the window. "I'd be home quicker than her."
"Dean's girlfriend knew?"
"Yeah, but I don't think she knew how much she used to come over."
"You really are used to sex each day. You must be disappointed with me, only giving you on the weekend."
"It's good sex, though," I assured her. "I'm happy with it."
"I'll try and give you more," she turned and promised, kissing my lips. "I will try to move to evening shift, too. Then you can fuck me every morning."
"Yuki, seriously. You worry too much," I said, kissing her mouth and holding her bare ass. "I'll take anything you can offer. Does not need to be every day. What about your family? Do we still need to be a secret? Can you at least say you have me as your boyfriend, so you can stay over?"
"Not possible," she said firmly. "My parents are not sex types. I will need to marry before I can stay with a man."
"Gee."
Yuki could feel my disappointment but there was no more time to discuss it, I had to run off to work. I was hungry but happy. Having Yuki volunteer her body to stick on the end of my cock was a privilege I appreciated.
When Yuki came over the next morning, I'd only just put my first load of cum in her when suddenly Dean was buzzing the doorbell.
"I don't get it," I flat-out said. "What's up? You know I'm with Yuki on Sunday mornings."
"Thought I'd come to watch," he smiled, walking in. Yuki was naked on the bed, dabbing tissues at her pussy.
"There she is," Dean grinned. "Fucked already?"
"Yes," Yuki said, not covering up. She shivered at the way he was looking at her, worried he was going to tell that she'd let him fully finger her the week before. And it was his hickeys on her breast.
"Dean. Don't need your help, mate," I said. "Don't you have anything to do today?"
"Not til lunch," he smiled. "You don't think Yuki would be up for what we did to that chic in Hiroshima?"
"Hey, Yuki's my girlfriend. That girl, she was just a friend. And anyway, Yuki's not ready for it. Not yet."
"Ask her," Dean shrugged.
